Hadalis

About This Game

Hadalis is a co-op deep-sea survival adventure where one wrong move can doom your entire crew. Whether diving solo or with your team, your mission is to descend into the hadal zone while preventing your fragile submersible from falling apart. Crushing pressure, hostile fauna, and critical system failures stand between you and the darkest region of the ocean. Will you make it back to the surface?

WORK TOGETHER

The deeper you go, the more your life depends on your crew. Coordinate repairs, manage oxygen, patch leaks, and keep each other calm as the hull creaks under extreme pressure. A single distraction can mean losing the entire dive.

DESCEND

Welcome to the Abyss:

Travel through multiple underwater layers, each with unique threats, from unstable caverns and volcanic vents to pitch-black zones where creatures track only by sound. Navigating hazards carefully is the only way to keep the sub intact.

SURVIVE

Everything Wants You Gone:

You’ll have to manage limited oxygen, lighting, and hull integrity while dealing with unpredictable sea life and environmental dangers. When systems fail and they will, you’ll scramble together to keep the dive alive.

DISCOVER THE DEEP

Uncover lost wrecks, strange organisms, and remnants of previous expeditions. The hadal zone hides more than just danger, only the bravest will uncover its mysteries.

MULTIPLAYER DIVING

Bring Friends… or Take the Risk Alone:

Invite up to three other divers to explore the abyss together, communicating through proximity chat to coordinate repairs and movements. Or dive solo if you dare face the deep without backup.
